Academic TutorThe perimeter of a shape is the total distance of the length of the lines that create the border and the area is the total amount of surface the shape takes up in a twodimension plane. An easy way to remember it is that the perimeter is the length of the fencing you would need to surround your yard, while the area is how much grass you'd need to completely cover it. 
QuestionCan area be calculated just from perimeter?Community AnswerNo. You could compute area from perimeter and shape, but not from perimeter alone.

QuestionWhich process would you use to obtain the area and perimeter of a particular room?DonaganTop AnswererAssuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.

QuestionHow do I find the perimeter of a rectangle?DonaganTop AnswererTwice the length plus twice the width.

QuestionHow would I get the area of a room with 6 sides?DonaganTop AnswererIf it's a regular hexagon, the formula is A = (3sÂ²âˆš3) / 2, where s is the length of a side. If it's not a regular hexagon, you would have to break down the floor plan into sections (squares, rectangles, and/or triangles), calculate the areas of each section, and add them together.

QuestionWhat is the perimeter of a triangle if all of the sides equal 11 m?Community AnswerThe perimeter of a triangle is all the sides combined, so if all the sides equal 11 meters, then it would be 11+11+11 since a triangle has three sides. The final answer would be 33.

QuestionHow can I find the perimeter of a sector?DonaganTop AnswererIf you mean a sector of a circle, you have to know the circumference of the circle and the central angle of the sector. Divide the central angle by 360Â°, express that as a fraction, and multiply that number by the circumference of the circle. That's the length of the sector's arc. Add to that twice the radius of the circle, and that's the perimeter of the sector.

QuestionA square has a perimeter of 14 feet. What is its area?DonaganTop AnswererDivide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. In this example, 14 Ã· 4 = 3.5. (3.5)Â² = 12.25 square feet.

QuestionWhat is a perimeter of a triangle?DonaganTop AnswererIt is the sum of the lengths of the sides.

QuestionWhat is the perimeter of a square with an area of 225?DonaganTop AnswererOne side of a square is the square root of its area, and the perimeter is four times the side.

QuestionDo you use area or perimeter to determine putting a wallpaper border around a room?DanoyachtcaptTop AnswererPerimeter. The word itself actually means "around the edge".

QuestionHow do I figure acres if i have 5 measurements (5 sides) of a piece of property?DonaganTop AnswererYou would also have to know all of the angles along the perimeter. You would then use geometry and/or trigonometry to find the area of the property (in square units) and then use the appropriate conversion factor to find the acreage.

QuestionHow do I find the area of steps?DonaganTop AnswererEach step has a length and a width (or dimensions of some sort). Use the formulas above to calculate the area of each step, then add them together.

QuestionHow can I find the area of a shape that's not closed?DonaganTop AnswererBy definition, an "area" is closed. If it's not actually closed, you will have to "close" it artificially before you can measure it in order to calculate the area.

QuestionHow do I find the perimeter of a rhombus?DonaganTop Answerer

QuestionCan we measure the perimeter of an open shape?Community AnswerNo. A perimeter is the distance all the way around a closed shape.

QuestionWhat is the process in finding the area and perimeter of a rectangle?DonaganTop AnswererTo find either, you would have to know both the length and the width of the rectangle. The perimeter is twice the length plus twice the width. The area is length multiplied by width.

QuestionA rectangular garden 6 meters wide has a diagonal measuring 10 meters, how do I find the perimeter?Community Answer2(6)+2(10)=32 meters. Multiply the width and length by 2 so that you can get the perimeter.

QuestionWhat if the area is 1 unit width and 1 unit length? Would the answer be 1 units for the area because 1x1=1?DonaganTop AnswererYes. The area would be 1 square unit (or 1 unit squared).

QuestionHow can I calculate the area of a parallelogram?Community AnswerMultiply base by height to calculate the area of a parallelogram.

QuestionHow can I find the area of a three quarter circle?DonaganTop AnswererMultiply pi by the square of the radius. Then multiply that by 3/4.

QuestionHow do I find the height of a rectangle if I know the perimeter and width?DonaganTop AnswererTake half the perimeter. From that subtract the width. That's the height (or length).

QuestionHow do I find the area of an irregular figure? It explained how to find perimeter, but not area.DonaganTop AnswererAn irregular shape must be subdivided into smaller shapes of known or calculable dimensions. Each area must be calculated and added together.

QuestionHow do I find the area and perimeter with only height and base?DonaganTop AnswererIf you're referring to a triangle, the area is half the product of the base and height. To find the perimeter, however, you would need additional information such as the other side lengths or the size of the angles. For other shapes, the requirements are different in each case.

QuestionHow do I get the area and perimeter of a right triangle if one side and angle is given?DonaganTop AnswererIt depends on which side and which angle are given. You would use known sides, angles and trigonometry to find the unknown side(s) and/or the height so you can calculate the perimeter and area.

QuestionHow do I find the perimeter and then the area of an irregular shape?DonaganTop AnswererThere are no formulas applicable to irregular shapes. Each such shape would have to be subdivided into smaller shapes of calculable dimensions and then added together.

QuestionHow do i find the area of only a quarter of a square?Community AnswerDivide by 4 like 4/4=1. So, cutting in quarters is how to find out the answer to the question
